EN D -LASTING MECHANISM.

To all whom it may concern:

Be it known that I, ARTHUR L. RUSSELL, a citizen of the United States,residing at Hyde Park, in the county of Norfolk and State ofMassachusetts, have invented certain Improvements in End-LastingMechanisms, of which the following description, in

connection with the accompanying drawings, is a specification, likereference characters on the drawings indicating like parts in theseveral figures.

This invention relates to, lasting machines and particularly to endlasting mechanlsms.

- wipers do not exactly fit the shoe, particularly if the shoe is madeon a crooked last a or a last very commonly in use, the outer that ashoe is not so accurately centered between the wipers that the wipers onthe two sides come over the last bottom to equal bearing with relationto the lip or shoulder of the innersole. Sometimes this is a result ofthe innersole being channeled in farther on one side than on the otherside of the toe. These considerations and others render it desirablethat the operator be able to give to one wiper additional movement ormovement different from or independent of the movement which the otherwiper is given, or that he be able to adjust the wipers on the two sidesof the toe end relatively to one another to fit or adapt the wipers tothe particular work being done. I have here mentioned the conditionsprevailing at the toe end of the shoe which call for the use of thisinvention and have herein illustrated theinvention as embodied in toelasting mechanism. Somewhat similar conditions to certain of thosementioned are also sometimes found at the heel of the shoe for the heelportions of lasts are often unsymmetrical. There is found particulardifli- Specification of Letters Patent. Application filed July 11, 1910.

culty in properly wiping into snugly lasted position the upper at theinner side of certam shapes of lasts at and adjacent to the breast ofthe heel or the end of the heel stifiener. a

The application of this invention to heel lasting wipers to enable thewiper acting on the inner side of a right or a left shoe to be adjustedup to the inner side of the heel portion of the last or to be movedinwardly over the last farther than the opposed wiper is moved will beobvious and requires no illustration. 7

It is a characteristic of the illustrated embodiment of this inventionthat either wiper may be advanced or retracted while the other wiperremains substantially stationary or is reversely moved. I If desired,either wiper may be so moved repeatedly with re lation to the otherwiper for overworking a stubborn or difficult portion of the shoe. Inthe construction herein shown by way of example to assist in theexplanation of the invention the .wipers and their supporting andguiding means, including the cam grooves in the wiper carriers forcontrolling the direction of the wiper closing movement, may be similarto a well known construction. Each wiper is connected with one member ofa split plunger which terminates in a rack bar. Between the rack bars isa pinion pivoted on a swinging lever by which the plunger members areactuated together to impart like movements to the wipers. A second leveror lever arm is mounted to turn in the swinging lever and has a wormconnection with the pinion by which the latter can be turned to move therack bars, plunger members and wipers relatively. The turning lever armis furnished with the handle by which the swinging lever is operated sothat the operator C2l/Il,Wlth the single hand which he is accustomed tousing for actuating the wipers, advance the wipers and also adjust orrelatively move them as the shape of the last or the condition of thework may require. By rotating the lever arm while advancing it he canaccelerate the movement of one wiper and retard that of the other and byrotating the hand lever while slowly advancing it he can advance onewiper while holding the other one substantially stationary. By suitablemanipulation one Wiper may be repeatedly advanced and retracted whilethe other remains substantially at rest and holds the upper inoverworked position under it. A friction lock controlled by a thumbpiece adjacent to the handle of the lever arm provides means for holdingthe mechanism as a whole while the lever arm is turned to advance andretract the wiper plates alternately.

The features above disclosed and other features of this invention,including certain combinations of parts and details of construction,will be understood from the following description of the illustratedexemplification of the invention and will be pointed out in the claims.

Figure 1 is a plan view of the toe lasting mechanism of a bed lastingmachine equipped with this invention and showing in full and brokenlines two positions of a shoe, or a right and a left last, to which theend embracing wipers are capable of being adjusted; Fig. 2 is aperspective View.

The wipers are plates 2, detachably con nected with Wiper holders 4c byclamps 5 supported in a lasting head 6 of known construction which isrotatable in a support 8 about a horizontal axis extendinglongitudinally of the machine. The wiper holders have cam slots 10 toreceive roller studs which project from the head and direct movement ofthe wipers inwardly as they are advanced so that the plates are closedtogether by like normal movements over the opposite sides of the endportion of the shoe. The wiper holders are each connected by links 12with one member 14 of a split plunger, the vrear end of each memberbeing formed as a rack bar in engagement with a pinion 15 locatedbetween the two bars. A lever 20 is connected by a link 21 to a fulcrumon the support 8 and receives loosely the shaft of the pinion 15.Swinging movement of lever 20 on its fulcrum thus acts through thedescribed connections to give like normal movements to the wipers. Thelever 20 has bearings 24 in which is rotatable a lever arm 25 providedwith the handle portion by which the lever 20 is to be swung. Therotatable arm 25 has a worm on its inner end which is in engagement witha toothed segment 28 fast on the shaft of the pinion 15. This connectionenables the pinion to be turned at any time, to move the wipersrelatively through the members and by that hand of the workman which isemployed in swinging the operating lever 20 of the divided plunger. Thelever 20 pivotally supports a friction pawl 30 which is spring pressedtoward locking engagement with a curved bar 32 that extends from thesupport 8. A thumb piece 34 extends into position to be engaged forreleasing the pawl by the operators hand which is manipulating the leverarm 25.

The nature of'th'e invention has been fully explained and its purposesand possible uses have been outlined with sufficient detail to enableothers to employ it in an end lasting mechanism of any suitable typeadapted for use at the toe or the heel of a shoe.
